(Cl. 9747) My invention relates to improvements in tracsides of said frame I, respectively, and having tor cult-ivators for use more particularly in pertheir front ends 6 secured, as by bolts I4, to said forming so-called corrugating operations, well frame l.

A rear transverse brace bar I0 contions between the same and the power plant 5. nects the beams 'I together adjacent the rear The crank disks 29 are operatively connected to ends thereof. A similar bar II extends across the links 29 by a pair of p'iston rods 3| one of Vthe beams 1 parallel with and adjacent to brace which extends between each disk and its related 50 bar I0 and with its ends connected to the outlink. The drive to the crank disks 29 may be side beams 1 by brackets as at I2. controlled by any Well-known type of clutch The described implement rig, or frame, is concontrol. The precise typelof-.oontrol being unnected to the front end of the chassis frame I important to tlepresent invention, such control by a `pair of draw bars I3 extending from opposite has notbeenillustrated in the drawings. 55

'I'he implements 9 are yieldingly held in the ground by a yielding connection extending between each link 20 and related bar I1 and comprising a bar 32 pivoted on and extending forwardly from the pivot 24 of each rod 23, and a tension spring 33 having one end connected to the front end of said link 20 as at 34, and its other end connected to the related bar l1 as at 35. As will be clear, the described yielding connection provides for vertical play of the implements 9 in the .ground independently of movement of the links 20 and rods 23 thereby obviating breaking the implements in the event the latter encounter obstacles such as rocks or roots.

The operation of the invention will, it is believed, be clear from-the foregoing without further explanation.

Manifestly the invention, as described, is susceptible of modification without departing from the inventive concept and right is herein reserved to all such modications falling within the scope of the claims appended hereto.

What I claim is:

l. The combination with a tractor including a. chassis and front and rear wheels, of an. implement-carrying rig mounted below said chassis intermediate said front and rear wheels and pivotally connected to said chassis for Vertical swinging movement, means for swinging said rig including a bar upstanding from said frame, a link swingably mounted on a fixed part of the tractor,

means for swinging said link in opposite directions including a crank disk rotatably mounted on a fixed part of the tractor, a pitman rod connecting said disk to said link, a rod pivoted to said link and slidable in said bar, a pin in said last-mentioned rod on one side of said bar whereby Inovement of said link in one direction correspondingly moves said bar and swings said frame, and a yielding connection between said link and said bar whereby the latter and the frame are movable independently of said last-mentioned rod and tensioned against such independent movement.

2. The combination with a tractor including a chassis and front and rear wheels, of an implement-carrying rig mounted below said chassis intermediate said front and rear wheels and pivotally connected to said chassis for vertical swinging movement, means for swinging said rig including a bar upstanding from said frame, a link swingably mounted on a xed part of the tractor, means for swinging said link in opposite directions, a rod pivoted to said link and slidable in said bar, a pin in said last-mentioned rod on one side of said bar whereby movement of said link in one direction correspondingly moves said bar and swings said frame, and a yielding connection between said link and said bar whereby the latter and the frame are movable independently of said last mentioned rod and tensioned against such independent movement.

JOSEPH PANCHERI.
